3 Claims. (01. 1513-41! This invention relates to the fuel reservoir for an oil burning heater including a portable tank and reservoir pan with cooperating parts applicable to an oil burning stove.

The purpose of this invention is to provide a fuel'oil reservoir for the usual household oil stove which will be convenient to handle in respect to refilling. Whereas most fuel oil reservoirs mounted in connection with such stoves requires the fuel oil to be carried in a separate, container from which it is poured into a tank, or wherein the reservoir includes a removable tank adapted to be filled away from the stove and setinto place in a reservoir pan after filling which is difficult and inconvenient, it is the purpose here to so construct and arrange the tank and reservoir pan that the tank may be readily and conveniently removed from the side of the stove with a minimum of efiort and inconvenience.

Thus, in the present invention the oil burning. stove is provided with a fixed reservoir pan provided with supporting slide members on each side thereof spaced from the bottom upon which the portable reservoir tank rests when in place and is slidablysupported and guided to permit it to be removed and replaced laterally thereof, all as will hereinafter more fully appear.

Another feature of the invention consists in providing the bottom of the reservoir tank with a. spring actuated control valve to be actuated by a raised formation in the bottom'of the reservoir pan for opening said valve when the tank is placed therein and automatically closing it when raised for removing it.

Another feature resides in the provision on the bottom of the tank of'guard devices such as will protect the valve. structure against actuation or damage when the tank is removed while permitting its free actuation when the tank is placed in the reservoir.

The full nature of the invention will be understood from the accompanying drawing and the following description and claims:

Fig. 1 is a side elevation of the back portion of the stove with an end elevation of the reservoir, including the tank and the reservoir pan, with a portion thereof in section. Fig. 2 is a rear elevation of the reservoir and the lower portion of the stove with portions of the reservoir pan and control valve shown in section. Fig. 3 is a perspective view of the reservoir tank and pan with the tank partially removed therefrom. Fig. 4 is an enlarged view of the valve and cap structure.

In the drawing there is shown the outer casing ll! of anoil burning stove upon therear side of which there is mounted a fuel oil reservoir having the usual oil line connection with the oil burning stove within the casing l0. V

The fuel oil reservoir comprises a reservoir tank H seatablewithin a reservoir pan l2. Said pan is supported by a frame comprising the de-; pending legs [3 which are secured to the housing H] by the flanges l4.

Spaced downwardly from the upper edge of the pan and extending inwardly from and secured to the side walls thereof, there is a pair of oppositely disposed tanksupporting and guiding shelves l5. Said shelves are so arranged as to receive and support the bottom of the tank H in spaced relation to the bottom of the pan and at the proper elevation therefrom to permit of the desired level of oil to be maintained therein.

Also, said shelves are spaced downwardly from the upper edge of the pan sufii'ciently to position.

and maintain the tank thereinwhile permitting of its ready removal through a sliding movement.

thereon in the manner shown in Fig. 3. g

The tank isprovided on atleast one end with.

a handle I6 adjacent the top thereof, which handle may begrasped for removing the tank.'

Its location adjacent the top thereof is important in that by reason thereof the tank may be lifted by the one handle while standing at one side of the stove, and caused toslide endwise at it's opposite end upon the shelves IS in position to ride over the upper end edge of the pan until freed therefrom. Thereupon the tank may be carried to a refill station in an angular depending position. At the refill station the tank is inverted so that the filler cap I1 is uppermost. Said filler cap may then .be unscrewed and the tank filled.

The filler cap is provided with a spring actuated valve, as shown in Figs. 2 and 4, wherein there is provided a valve head [8 for controlling the discharge orifice IS in the cap. Said valve is provided with a normally downwardly extending plunger 20 and is maintained in closed position under spring tension by a spring '2! bearing against the valve and a spring retainer 22. For.

protecting said plunger in the removal and handling of the tank a pair of bowed wire guards 23 are secured to the bottom of the tank in such manner as to extend to a position below the plunger on each' side thereof. I Thus, when the tank is caused to slide over the end edge of the pan, as in Fig. 3, it will slide upon the guards 23 so as to carry the plunger free thereof and preto vent contact. It is to be noted that when the tank is raised for removal from the pan, the spring 2| will seat the valve 18 and close the opening in the cap 11.

After filling of the tank, it is replaced in the pan by first setting the lowermost end edge on the shelves l5 at the near end of the pan. Thereupon the tank may be caused to slide'endwise on said shelves until itr'eaches. the opposite end of the pan and is freed to be lowered into seated position. To permit thereof the guards 23 are so positioned and spaced that they ride. inside of. the shelves and do not engage therewith. i

For controlling the valve through the plunger 20 the central position of thebottom off the pan is provided with a cammingsurface 24' extending; upwardly into the path of the plunger, but be; tween the guards 23 so as not to be engaged: By means of this cam'ming surface formed on the bottom of the pan, the valve F8 thereby.

will be automatically opened when the tank is lowered into seated position, and automatically closed when thetank is raisedfrom seated position for removal. When the valve .is thus opened, oil is permitted to flow intothe pan to a level controlled by the valve openin and bem'aina tained at such levelso long as any oil. remains, in the tank. The bills fedin the usual mann'er from the bottom of the reservoi'r'pan 12 through the feed line 25 through the. valve control unit 26 and line 2! ing l0.
